Bio‐Based Sodium Alginate Beads Reinforced With Microalgae (Limnospira platensis): Structure–Property Relationships and Controlled Release Potential

Journal of Applied Polymer Science, EarlyView.
Development of sodium alginate beads doped with Limnospira platensis, designed for the gradual release of nutrients and bioactive molecules into soil. The biomaterial combines biodegradability, controlled‐release potential, and microalgal biomass valorization, contributing to reduced nutrient losses through leaching and the development of more ...

THE INFLUENCE OF SYNTHESIS PARAMETERS ON MICROCRYSTAL STRUCTURE ARTIFICIAL HYDROXYAPATITES (HAP) [PDF]

, 2023
The phase composition and crystal structure of hydroxyapatites (HAP) obtained by chemical precipitation have been studied by X-ray phase analysis. During the experiment, samples annealed at 700 °C have a structure close to human tooth enamel and are ...

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Fe-Doping-Induced Magnetism in Nano-Hydroxyapatites

, 2017
Doping of biocompatible nanomaterials with magnetic phases is currently one of the most promising strategies for the development of advanced magnetic biomaterials. However, especially in the case of iron-doped magnetic hydroxyapatites, it is not clear if
